At 15 years old and smoking 2 to 3 cigarettes a day, Nicotex (nicotine gum) is not recommended for self-use. Nicotine replacement therapy is typically approved for adults over 18. Because your daily cigarette consumption is very low, using nicotine gum might unnecessarily keep you dependent on nicotine. The safest and most effective approach for you to quit is through counseling, lifestyle changes, and support groups, rather than medication. Please consult a pediatrician or healthcare provider before starting any nicotine replacement products so they can help you create a safe, personalized plan to quit.
